We almost spat out our coffee in surprise when we saw Katy Perry on the red carpet for last night's Creators Party Presented by Spotify. The pop star was straight-up twinning with Kim Kardashian West, from her sheer corset top (which is probably the most Kardashian item of clothing of all time—of all time!) to her long, sleek boxer braids.

While Kardashian's look inspires tons of copycats—like her most recent doppelganger—this still surprised us. Perry's all about originality. She dreams up out-there touches, like cupcake bras and violet hair, and always makes them her own (although, to be fair, she *did *borrow Snooki's signature look for the Golden Globes). We're not going to lie: It's a bit weird to see her partake in a big trend like this.

We think we've figured out the connection. Besides braids, the two have one big thing in common: celebrity hairstylist Jen Atkin, one of our 35 beauty superstars under 35 and founder of the new (and seriously popular) haircare line, Ouai. "We wanted something that was rock 'n roll to go with Katy's outfit," says Atkin, who created the style for Perry. That's why they went for boxer braids, which have a tough, tomboy-ish vibe to them. We're still convinced Mrs. West could have a been a source of inspiration—especially since Atkin captioned her Instagram of the look with "Insert dancing KIMOJI here"—but either way, we call it a winner.
